三款型号的参考位置 Reference position of the three models
现有资料中，YT23、YT27与YT28均属于气腿式凿岩机。可先比较重量、机身长度、参考孔径、耗气量、冲击频率和钎尾规格，再结合现场条件缩小候选范围。 All three are air-leg drills. Compare weight, length, reference diameter, consumption, frequency and shank, then shortlist against site conditions.
为什么还要逐单确认 Why order-specific confirmation matters
参考数据不能自动等于实际出厂配置。气腿、注油器、钎具、包装与备件需求需要写入询价和确认文件。 Reference data is not automatically the actual factory configuration. Include air leg, lubricator, tooling, packaging and spares in inquiry and confirmation documents.
